How to access Web-Client admin-app on vCenter Server 5 Appliance?

Hello Everybody,

as stated above I have troubles accessing the Web-Client admin-app on my vCenter Server 5 deployed via Appliance.

as mentioned here:

http://www.virtualizationadmin.com/articles-tutorials/vmware-esx-and-vsphere-articles/general/getting-starting-vsphere-5-web-client.html

you can access the Manamegemnt interface for Webclient via: https://localhost:9443/admin-app

since I dont have a Windows underneath and the Appliance does not allow command-line browsers like lynx I can't access it locally.

But when I try to manage it form another computer I get the error:

Clik here to view.vSphere Web Client administration tool cannot be accessed from a remote host.

Therefore simple question: How can I access it?

Thanks in Advance,

aschneid
